> I'd be interested in a demo showing that ColDet is faster. have a look at this http://www.tu-ilmenau.de/~atzek/kamikaze.zip there are two kamikazeversions: one for coldet and one for opcode. if you look at the colldet (collisiondetection) times in the right top corner of the screen you see, that coldet is always faster. btw: how can i reply to a thread of this mailinglist ?
